We are visiting family in South Hampshire this weekend so don't want to spend the whole time indoors but obviously quite worried about spending much time in the sun when it's going to be so hot, particularly on the Saturday. We were originally going to go to the beach, which will feel cooler, but is very exposed and I don't think any amount of sun cream and hats will be sufficient. Any ideas what we can do instead to still have a good time but without being in the sun for very long?
